Hi, CP2K Community,<br><br> I am looking for a subroutine to calculate transition dipole moment between two KS orbitals (or two basis set functions). Please let me know whether there exists such a subroutine, or there is an alternative way.<br>
<br> Specifically, what I need is <phi_A | x | phi_B> <br><br> Thanks.<br><br>Hanning<br>
